Severe renal dysfunction (estimated glomerular filtration rate \\< 30 mL/min/1.73 m2 at the Screening visit; calculated by the local laboratory to assess safety) or is on chronic dialysis\n10. History of malignancy within the past 2 years prior to treatment Day 1 requiring chemotherapy and/or radiation (with the exception of local therapy for non-melanoma skin malignancy)\n11. History of unstable or deteriorating cardiac or pulmonary disease within 6 months prior to consent including but not limited to the following:\n\n 1. Unstable angina pectoris or myocardial infarction or elective coronary intervention\n 2. Congestive heart failure requiring hospitalization\n 3. Uncontrolled clinically significant arrhythmias\n 4. Pulmonary hypertension\n12. Criteria related to ECG parameters:\n\n 1. PR interval \\> 220 msec in any participant\n 2.

QRS interval \\> 120 msec in participants with newly (within 3 months) emerged bundle branch block\n 4. A participant with stable bundle branch block with or without stable cardiac disease may be enrolled; QRS interval \\> 120 msec and QTcF interval \\> 480 msec are acceptable in these participants.\n13. Any condition affecting drug absorption, such as major surgery involving the stomach or small intestine (prior cholecystectomy is acceptable)\n14.

Inadequate venous access as determined by the Investigator/site staff\n16. Medical, psychological, or behavioral conditions, which, in the opinion of the Investigator, may preclude safe participation, confound study interpretation, interfere with compliance, or preclude informed consent\n17. Received erythropoietin or other hematopoietic growth factor treatment within 28 days of signing ICF or is anticipated to require such agents during the study\n18. Ongoing or recent (within 2 years) substance abuse\n19. Known allergy to voxelotor\n20.
